MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent N 0. 641,014, dated January 9, 1900.

Application filed July 2'7, 1898. Serial No. 686,980. (No model.)

To all whom it may concern:

Be it known that I, HENRY W. HONEYMAN, a citizen of the United States, residin gin Paw tucket, in the State of Rhode Island, have in vented a new and useful Mechanical Movement Especially Designed for Operating Tentering-Machines, of which the following, with the accompanying drawings, is a description.

There have been various attempts within the past few years to obtain a satisfactory mechanism by means of which the chains of tentering-machines carrying the cloth may be driven at an even and regular speed; but all inventions and adaptations known to me are open to more or less serious objections. I believe the mechanism which I am about to describe as my invention, combining mechanism for swinging the rails of the tenter with mechanism for driving the tenter-chains, will be found to accomplish what is desired in this class of mechanism better than any heretofore employed.

Figures 1 and 2 are respectively a plan and side elevation of one end of a tentering-machine, showing my invention applied to it. Figs. 3 and 4 are sectional views of my invention. Figs. 5, 6, 7, 8, and 9 are views of sundry details; and Fig. lOis a sectional view very similar to Fig. 3, but showing a slightlymodified arrangement.

In the drawings, A A represent two heads, one for each side of the machine, eachcontaining the mechanism for operating one of the rails and the cloth-chain carried by it. These heads are mounted upon abed B, running transversely of the machine, and are arranged to slide thereon whenever the machine is set at different widths for different widths of the cloth to be treated. Each head consists of a casting with a hollow space in the direction of the length of the tenter, (see especially Fig. 3,) in which space is mounted an engine-crank O, driven by gears D and D on the outside of each head. In order to mount the crank in the head, there is a faceplate A attached to each side of the head, which plates carry the bearings for the crankshaft. Upon the top of each head is a piece E, Figs. 3 and 4, arranged in slides formed in the heads themselves, so that it may slide back and forth, and attached to the under side of this slide E and in the open space in the center of the head A is a downtvard-projecting open box or arm E, Figs. 3

and 4, which also has slides upon its inner surfaces, and within this box or arm 1 and sliding upon the slides within it is the crankbox F upon the engine-crank C. By the de scription thus far it is evident that the sliding piece E will be given areciprocatingmotion back and forth as the crank O is driven by the gears D and D. This reciprocating motion of these sliding pieces Eis communicated to the side rails of the machine to give them the ordinary swinging motion of such machines, while the heads A A remain stationary, in the following manner: The side rails of the tenter as ordinarily constructed really terminate in my machine at the first cross-arm -H, Figs. 1 and 2, it being under stood that there are a number of such arms supporting the side rails in the machine, although it is not necessary to show them in the drawings. The side rails are continued between the cross-arm H and the heads AAby the connecting-pieces G G, which are connected at one end to the sliding pieces E E and at their other ends to the cross-arm H. The connections at both ends of these pieces G G are pivots, so as not to intefere with the swinging motion of the rails, the pivot at the arm H being constructed in any usual manner and that between the pieces G G and the slides E E preferably in the manner hereinafter described. It will be seen that the reciprocating motion of the slides E E is communicated to the pieces G Gthrough the connection between them and from the pieces G G to the arm H by their connection with the latter. The intermediate pieces G G are constructed in the same manner as the side rails of the machine, including the ordinary guideway for the cloth-chains, and form continuations of those rails, the only object in making them separate from the rails being to provide the pivoted joints to allow of the heads A A being made stationary. Near the ends of these pieces G G on the heads A A are located sprocket-wheels I I, Figs. 1 and'2, to drive the chains.

Having described the essential features of the mechanism for swinging the tenter, I will now describe that portion of the mechanism by which the chains are driven through the sprocket-wheels I I.

Attached to the crankrbox F, Figs. 3 and 4, is an upright shaft K, which is caused to reciprocate vertically by the revolution of the too crank-shaft. A long sleeve K preferably surrounds this upright shaft K for the greater part of its length and is caused to also reciprocate vertically by the nut K above it on the end of the shaft K. A long spline or feather K is inserted in the sleeve K. The sleeve K and spline slide through and drive a gear L. This gear L has a long hub extending through the slide E and the connecting rail-piece G and is prevented in any ordinary mechanical Way from moving vertically with the shaft K. The hub of the gear L thus connects the slide E with the connecting rail-piece G, the center of the shaft K being the pivot, thus permitting the piece G to adapt itself to the swinging motion of the rails of the machine and at the same time giving them their reciprocating mot-ion. The motion about the pivot, however, is extremely slight. In order to give rotary motion to the sleeve K, and thereby drive the gear L, I attach a beveled gear M, Figs. 3 and 4, to the lower end of the sleeve just above the crankbox F and mount a corresponding beveled gear N, Fig. 3, to mesh with it rigidly upon the cross-arm or connecting-piece of the crank C. It is evident that as the crank revolves the gear M will be driven by the gear N, thus imparting a rotary motion to the sleeve K and gear L. The gear L may drive the sprocket-wheel I either directly by being attached thereto or through intermediate gears, such as I have shown in Figs. 1 and 2 of the drawings. The advantage of the latter is that they may be readily mounted so as to be thrown out of mesh, as shown in the drawings, when it is desired to stop the chains Without stopping the swinging motion of the tenter, and also may readily be changed and by substituting gears of different sizes make it possible to vary the speed of the chains relatively to the swinging motion given the tenter-frame.

The prior description contains enough not only to show how the sprocket-wheels I and chains are driven by my invention, but also to point out the essential features necessary to impart the swinging motion to the machine; but in a practical machine of this kind it is necessary to vary at times the extent of the reciprocations to and fro of the machine, and I will now point out the construction I have adopted to accomplish this. Instead of constructing the entire driving-shaft and engine-crank of one piece I make two diskplates P P, Figs. 3 and 4, for each head and attach each disk-plate to a piece of shaft mounted in the bearings in the plates A A. One of these disk-plates is shown separately in Figs. 5 and 6. Across the center of the face of each plate are cut guideways for sliding piecesR R, (see same figures and Figs. 7 and 8,) and the cross-shaft of the engine-crank is rigidly attached to these pieces R R. It is evident that by setting these pieces R R in such manner that the cross-shaft will be ata greater or less distance from the center of the disks P P, where the driving-shaft is located, the reciprocating motion given the rails, as above described, will be greater orless. These plates and the connecting-shaft may be readily set as desired when the machine is stopped in such a position that they may be moved longitudinally across the disks P P-that is to say, stopped in a position one-fourth of a revolution farther than the position shown in Figs. 3 and 4,which latter position was adopted for the drawings to show the parts more plainly. When thus stopped, the rails of the machine may be moved to the required extent either by hand or by machinery. As indicated in the drawings, Figs. 1, 2, and 4, I have attached a handle Z, pivoted in an extension of the head, and connected this hanslides out in the disks P P. In practice, however, on account of the great weight of the machine some other mechanism for accomplishing this purpose will very likely be more advantageous for this purpose; but such mechanism can readily be added by any competent mechanic without changing my invention.

When the pieces R R are set to give the desired amount of reciprocation, they must be firmly held in that position. The means I have adopted consist in cutting slides in the faces of the pieces R R (see Figs. 7 and 8) with angular sides and placing within them binding-pieces S S, (shown separately in Fig. 9,) each of which is attached to a rod T, running through the center of one of the bear-- ing-shafts of the crank,which are made hollow for this purpose. Upon the ends of these rods T T and in the binding-pieces S S screwthreads are cut, and there are hand-wheels T upon the other ends of the rods T to operate the screw-threads, and thus draw the bindingpieces S S against the angular sides of the slides in the pieces R R and firmly hold them in proper position. (See Fig. 3.) It is evident that other mechanism for holding these pieces in proper position may readily be adopted, as well as mechanism to both set them and hold them combined in one. While it is practically necessary to supply means for varying the amount of reciprocation in the rails of the machine, it is not necessary to make these changes very frequently.

The sleeve K is not an essential feature of myinvention. It is only a convenience in constructing and arranging the parts. A solid shaft might readily be used in the same position as the shaft K and sleeve K, being connected to the crank so as to be given longitudinal motion and to keep the gearing always in mesh, and yet being so mounted as to be free to rotate, as any competent mechanic will readily understand. Such a modified arrangement is shown in Fig. 10.

For convenience I have used in the claims the pieces R R in any position desired in the the single term shaft to cover either of these constructions or any similar construction, the sleeve Kin fact constituting only a part of the shaft K.

Many other of the details above described may be more or less varied without departing from the spirit of my invention.
